Tools/ue_build_demo_map.py builds /Game/Hollywood/DemoMap: sun, sky, the hero facade on the building line, six site meshes imported with collision, and a player start on the north sidewalk. Tools/ue_import_site.py imports the site FBXs; terrain, road and sidewalks use complex-as-simple so a simple hull cannot ramp over the kerbs. Art/blender/site/export_site_fbx.py exports one FBX per object so each can carry its own collision. Reset (R) and pause (Escape) join the character and the input context: reset restores the spawn transform and clears momentum, pause is a real game pause that releases the cursor. DefaultInput.ini captures the mouse on launch. Three placement defects found by measuring the imported actors rather than trusting the plan: the spawn was on the wrong sidewalk because the FBX flip inverts north, a mirror I added to the exporter double-corrected an already correct sidewalk, and the street meshes only carry part of the north walk - the rest is terrain.
